Standard methods of measurements are with several divisions which provides list of descriptive features of work. For an example in CESMM3, has three divisions and SMM have five divisions.

E.g. Class D in CESMM3 (Item 4 &5)

Division 1 – Buildings/Other structures

Division 2 – Brickwork/Concrete

Division 3 – Volume not exceeding 50m3/ 50-100m3

In some divisions it has provided descriptions with hyphen mark(-), e.g. 50-100m3.

Some Qs’s may not clear about the meaning of hyphen mark used in standard method of measurements.

Simply 50-100 means; all numbers from 50 to 100,
excluding 50 but including 100.

Then will see what has stated in few standard methods of measurements.

CESMM3 has stated that “ A hyphen between two dimensions means a range of dimensions which includes all dimensions exceeding that preceding than hyphen but not exceeding that following then hyphen.“

SMM7 has stated that “The use of hyphen between two dimensions in this documents or in bill of quantities shall means a range of dimensions exceeding the first dimension stated but not exceeding the second.”
